PRP for Hair Regrowth
Platelet-rich plasma (PRP) therapy stimulates hair growth through vascularization and angiogenesis, and encourages hair follicles to extend the duration of the anagen phase of the growth cycle. PRP therapy for hair loss is shown to increase blood supply to the hair follicle, triggering natural hair growth.
Growth factors found in PRP include several intracellular structures such as glycogen, lysosomes and alpha granules that promote the healing and repair process. These help to reawaken the activity of the hair follicles and promote new hair growth. The use of PRP is scientifically shown to increase hair count, hair thickness, and the growth phase of the hair cycle.
PRP Growth Factors
PRP specific cells that promote hair growth include:
- Platelet-Derived Growth Factor (PDGF)—promotes blood vessel growth, cell replication, skin formation;
- Transforming Growth-Factor-Beta (TGF-b)—promotes growth of matrix between cells, bone metabolism;
- Vascular Endothelial Growth Factor (VEGF)—promotes blood vessel formation;
- Epidermal Growth Factor (EGF)—promotes cell growth and differentiation, blood vessel formation, collagen formation;
- Fibroblast Growth Factor-2 (FGF-2)—promotes growth of specialized cells and blood vessel formation; and,
- Insulin Like Growth Factor – (IGF)—a regulator of normal physiology in nearly every type of cell in the body

Hair Regrowth Process
PRP for hair regrowth begins with a standard blood draw from the patient’s arm. The tube of blood is put into a centrifuge to separate the red blood cells from the plasma. Then the plasma, rich in platelets, is removed from the tube and injected directly into a patient’s scalp at the hair follicles. Injections are typically spread across a half-inch area of thinning hair to ensure dense coverage.
Treatments are typically performed monthly for the first three to four months, and then every three to six months thereafter. This schedule is optimal for stimulating hair growth factors and stem cells associated with reducing hair fallout. PRP has proven to combat hair loss in more than 70% of cases.
Before-and-after PRP for Hair Regrowth
“I think PRP is a breakthrough because it’s a natural substance that can regrow hair, with virtually no side effects,” says Dr. Jeffrey Rapaport. “It’s also used to speed up the healing process in any procedure that disrupts the epidermis, such as a laser and micro-needling, and by orthopaedic surgeons for tendon injuries and bone recreation.”
